January Jones looks supernaturally buxom on the November cover of GQ. “They definitely did some significant retouching,” claims a source close to the magazine, citing other images of Jones in which the “Mad Men” star appears a lot less curvy. “It’s just par for the course these days with cover shoots.”

GQ, however, denies any funny business. In a blog post on the monthly’s newly redesigned Web site titled, “Yes, they’re real. And they’re spectacular,” photo editor Dora Samo says: “People think that a person will look the same in every photograph, but that just doesn’t happen . . . Terry [Richardson] likes to work with harder lighting, and that can create a stronger shadow — that, and body position and perspective could give the illusion that her breasts are bigger. January Jones needed no help. Trust me.” A rep for Jones didn’t respond to requests for comment.
